在计算节点配置内核参数：
vi /etc/sysctl.conf
net.ipv4.conf.all.rp_filter=0
net.ipv4.conf.default.rp_filter=0
在计算节点使内核参数立即生效：
sysctl -p
在计算节点安装软件：
yum install -y openstack-neutron-ml2 openstack-neutron-openvswitch
在计算节点修改配置文件：
openstack-config --set /etc/neutron/neutron.conf DEFAULT rpc_backend rabbit
openstack-config --set /etc/neutron/neutron.conf DEFAULT rabbit_password 123456
openstack-config --set /etc/neutron/neutron.conf DEFAULT rabbit_hosts controller1:5672,controller2:5672,controller3:5672

openstack-config --set /etc/neutron/plugins/ml2/ml2_conf.ini agent tunnel_types gre
在计算节点启动服务：
systemctl enable openvswitch.service
systemctl start openvswitch.service
在计算节点修改配置文件：
openstack-config --set /etc/nova/nova.conf DEFAULT network_api_class nova.network.neutronv2.api.API
openstack-config --set /etc/nova/nova.conf DEFAULT security_group_api neutron
openstack-config --set /etc/nova/nova.conf DEFAULT linuxnet_interface_driver nova.network.linux_net.LinuxOVSInterfaceDriver
openstack-config --set /etc/nova/nova.conf DEFAULT firewall_driver nova.virt.firewall.NoopFirewallDriver
openstack-config --set /etc/nova/nova.conf neutron url http://myvip:9696
openstack-config --set /etc/nova/nova.conf neutron auth_strategy keystone
openstack-config --set /etc/nova/nova.conf neutron admin_auth_url http://myvip:35357/v2.0
openstack-config --set /etc/nova/nova.conf neutron admin_tenant_name service
openstack-config --set /etc/nova/nova.conf neutron admin_username neutron
openstack-config --set /etc/nova/nova.conf neutron admin_password 123456
在计算节点创建符号链接、拷贝等操作：
ln -s /etc/neutron/plugins/ml2/ml2_conf.ini /etc/neutron/plugin.ini
cp /usr/lib/systemd/system/neutron-openvswitch-agent.service \
/usr/lib/systemd/system/neutron-openvswitch-agent.service.orig
sed -i ‘s,plugins/openvswitch/ovs_neutron_plugin.ini,plugin.ini,g‘ \
/usr/lib/systemd/system/neutron-openvswitch-agent.service
重启相关服务：
systemctl restart openstack-nova-compute.service
systemctl enable neutron-openvswitch-agent.service
systemctl start neutron-openvswitch-agent.service
验证：
source admin-openrc.sh
neutron agent-list
